Last week's jobs report for July showed unemployment dropping from 7.6% to 7.4%, which marks the lowest rate since December 2008. Good times, right? Not exactly. The rate fell in part because more and more Americans have ceased looking for work. Wage growth has been anemic and the recovery from the recession has been the slowest since World War II. The U.S. economy is sputtering along at 2% growth.

But there are places with strong business climates, fueled by low costs and educated labor forces. With that in mind, Forbes crunched the numbers for our 15th annual list of the Best Places For Business And Careers.

Des Moines, Iowa, tops our list this year. It is the only place that ranks among the top quartile in at least nine of the 12 metrics we graded the cities on.

Principal Financial, headquartered in Des Moines, is putting $250 million into an expansion of its downtown campus.

Tech giants and are also branching out in central Iowa. Facebook announced plans in April to invest $300 million to build its fourth owned and operated data center.

Provo, Utah, ranks second on the strength of a humming economy, which grew 6% last year to $18 billion. The metro area also had the country's top job growth of 5%. Brigham Young University is a stabilizing force for the area and the largest employer in Provo.

Raleigh, N.C., has been a perennial in our top five and this year ranks third. Employers are able to tap the top universities in and around the metro area like Duke, the University of North Carolina and North Carolina State. They provide a steady stream of educated, young cheap labor. College attainment levels in Raleigh are 41%. People continue to flock to Raleigh, which had the second highest rate of net migration of any metro area over the past five years.

San Antonio leads five Texas cities in the top 25 of our list. San Antonio, like much of Texas, benefits from business costs that are 19% below the national average. Job growth in the Alamo City has been strong in healthcare and bioscience, as well as energy and information technology.

To gauge the best places for business in the U.S., we rate the 200 largest metro areas on a dozen factors related to jobs, costs (business and living), income growth, quality of life and education of the labor force. Forbes uses data from economic research firm Moody’s Analytics, the U.S. Census and demographer Bert Sperling, who runs Sperling’s BestPlaces (click here for a more detailed methodology).

California cities dominate the bottom of our ranking, taking four of the last five spots. Salinas, Stockton, Merced and Modesto are all plagued by flat or negative income growth, sky-high unemployment and an uneducated labor force (only 12% of adults have a college degree in Merced).

Atlantic City brings up the rear, ranking 200th. The New Jersey gambling and convention destination has been hammered by the economic downturn and increasing gambling options in surrounding states. The numbers paint an ugly picture. Unemployment has hovered near 13% and employment has fallen 1.9% annually the past five years. Business costs are 8% above the national average and there has been a steady net migration out of the area since 2007.
